Glucophage XR 1000 mg Tablet

Glucophage XR 1000 mg tablet is an extended-release oral diabetes medicine containing metformin hydrochloride. It is primarily used to help control blood glucose levels in people with Type 2 diabetes mellitus, together with an appropriate diet, physical activity, and other lifestyle measures.

The letters XR mean extended release. Unlike standard immediate-release Glucophage, the XR formulation releases metformin gradually over a longer period. This can allow less frequent dosing and may improve gastrointestinal tolerability for some patients.

Glucophage XR is available in different strengths, which can vary by market. Patients should always check the strength printed on their medicine pack and follow the dose prescribed by their healthcare professional.

Primary Uses of Glucophage XR

Glucophage XR is mainly used for:

• Type 2 diabetes mellitus
• High blood glucose
• Improving insulin sensitivity
• Long-term blood glucose management
• Combination therapy with other diabetes medicines
• Combination treatment with insulin when required

Metformin may also be prescribed in selected patients for conditions associated with insulin resistance or polycystic ovary syndrome (PCOS). These uses should be based on individual medical assessment.

How Does Glucophage XR Work?

Metformin primarily reduces the amount of glucose produced by the liver and improves the body’s sensitivity to insulin. This allows tissues to use glucose more effectively and helps lower elevated blood glucose levels.

When used alone, metformin has a relatively low risk of causing hypoglycemia. However, low blood glucose can occur when Glucophage XR is combined with insulin or certain other antidiabetic medicines.

What Does XR Mean?

The extended-release formulation is designed to release metformin slowly after the tablet is swallowed.

This has several potential advantages:

• More gradual release of metformin
• Convenient dosing schedules for some patients
• Potentially fewer gastrointestinal side effects in some people
• More sustained delivery of the medicine

Glucophage XR tablets should generally be swallowed whole. They should not be crushed, chewed, or broken unless the specific product information says otherwise, because doing so can interfere with the extended-release mechanism.

How to Take Glucophage XR

Take Glucophage XR exactly as prescribed.

It is commonly taken with food, often with the evening meal depending on the prescribed regimen. Taking metformin with food can help reduce digestive side effects.

The appropriate dose depends on:

• Blood glucose levels
• HbA1c
• Kidney function
• Current metformin treatment
• Other diabetes medicines
• Individual tolerance

Doctors may gradually increase the dose according to the patient’s response and tolerance.

Common Side Effects

The most common side effects of metformin involve the digestive system and may include:

• Diarrhea
• Nausea
• Abdominal discomfort
• Vomiting
• Reduced appetite
• Metallic or altered taste

These effects are often more noticeable when treatment begins and may improve with continued use.

Extended-release metformin may be better tolerated by some people who experience gastrointestinal problems with immediate-release metformin.

Vitamin B12 Deficiency

Long-term metformin use can reduce vitamin B12 levels in some patients. The risk may increase with higher doses and longer treatment duration.

Patients experiencing persistent fatigue, weakness, pins and needles, numbness, a sore tongue, or symptoms of anemia should discuss these symptoms with their healthcare provider. Periodic vitamin B12 testing may be appropriate for some long-term users.

Lactic Acidosis

Lactic acidosis is a very rare but potentially serious complication of metformin therapy. The risk increases when metformin accumulates in the body, particularly in people with significant kidney impairment or certain serious illnesses.

Urgent medical attention should be sought if a patient taking metformin becomes severely unwell with symptoms such as difficulty breathing, severe weakness, persistent vomiting, abdominal pain, unusual drowsiness, or feeling unusually cold.

Kidney Function

Kidney function should be assessed before starting metformin and monitored periodically during treatment.

Patients with significant kidney impairment may require dose adjustment or may not be suitable for metformin therapy.

Healthcare professionals should also be informed about Glucophage XR use before certain imaging procedures involving iodinated contrast agents, because metformin may need to be temporarily stopped in some circumstances.

Glucophage vs. Glucophage XR

Feature	Glucophage	Glucophage XR
Active ingredient	Metformin	Metformin
Formulation	Immediate release	Extended release
Release	Faster	Gradual
Dosing	May require multiple daily doses	Often less frequent
GI tolerability	GI effects can occur	May be better tolerated by some patients
Crush/chew	Depends on formulation	Generally should be swallowed whole

The two formulations contain the same active medicine but should not automatically be substituted dose-for-dose without medical advice.
